-Changed: Several parts of the library involve interfacing with

-examples are the interfaces to the SUNDIALS solvers (e.g., the

-Fixed: When used with the linear-polynomial MappingQCache(1),

-Fixed: SolverCG used with matrices and preconditioners that support
-interleaving of the vector updates with the matrix-vector product (e.g. with
-certain matrix-free operators) sometimes performed the final update to the
-result vector `x` with a wrong coefficient. This could affect the returned
-solution for coarse tolerances far away from convergence. This is now fixed.

-Fixed: It was previously possible to assign scalar values to
-Tensor and VectorizedArray objects that were temporaries -- say in expressions
-such as
-```
- VectorizedArray<...> my_function();
- ...
- my_function() = 1.234;
-```
-This does not make any sense: What `my_function()` returns is a
-temporary object, and assigning a value to it has no consequences
-because the temporary object dies at the end of the line. Whatever the
-programmer intended to do here was almost certainly a mistake.
-
-As a consequence, this is now prohibited and the compiler will produce
-an error when trying to do this.

-Fixed: Mesh files in COMSOL's `.mphtxt` format are often created on

-Fixed: Consider the following scenario: You initialize a DoFHandler with a
-parallel::distributed::Triangulation, and afterwards you want to create the
-Triangulation by calling Triangulation::create_triangulation() that takes a
-TriangulationDescription::Description as an argument. This caused an issue
-as the active FE tables of the DoFHandler have not been properly updated
-during the creation of the Triangulation. This is fixed now by treating the
-resulting Triangultion as a 'fresh' one by triggering Triangulation::Signals::create
-at the end of Triangulation::create_triangulation(), which in turn
-reinitializes the DoFHandler.
